These post-top or suspended luminaires are designed to comply with the **Regulation on Energy Efficiency in Outdoor Lighting Installations (RD 1890/2008, Spain)**, ensuring optimal light distribution on roads, squares and pedestrian areas. **Outdoor lighting: Energy efficiency and regulatory compliance** ----------------------------------------------------------------- In technical specification, the lantern is not only evaluated as an ornamental element but as a tool of lighting engineering. The implementation of high-efficacy LED modules (above **130 lm/W**) allows a significant reduction in energy consumption compared to discharge technologies, while maintaining illuminance uniformity in accordance with **EN 13201**. ### **Light pollution control (ULORinst)** One of the critical parameters in the selection of a lantern is the **installed Upward Light Output Ratio (ULORinst)**. To comply with night-sky protection regulations, especially in areas of special astronomical protection, our technical lanterns guarantee **ULORinst < 1%**. This is achieved through internal optics that direct the flux exclusively towards the lower plane, eliminating the emission of direct light towards the upper hemisphere. ### **Thermal management and L90B10 service life** System longevity is determined by the heat dissipation of the optical block. The use of low-copper die-cast aluminium bodies and passive thermal management systems makes it possible to certify a service life of **L90B10 > 100,000 hours**. This figure is fundamental for reducing operational and maintenance costs in energy services contracts (ESCO). ### **Road optics and advanced photometry** Photometric versatility is essential to adapt to different road geometries. The lanterns incorporate optical-grade PMMA lenses with **symmetric, asymmetric or road** distributions, allowing increased spacing between supports without compromising uniformity or generating disturbing glare (G3/G4 according to the standard). ### **Connectivity and Smart City (NEMA/Zhaga)** To facilitate the transition to smart cities, today's lanterns integrate standardised connectors such as **7-pin NEMA** or **Zhaga Book 18**. These interfaces enable "plug-and-play" installation of remote management nodes, motion sensors or photovoltaic cells, enabling point-to-point control and real-time consumption monitoring. ### **Comparative Table of Technical Specifications** **Technical Specification****Standard Configuration****Configuration for Historic Centres****Colour Temperature (CCT)**3000K - 4000K2200K / PC-Amber / 2700K**Luminaire Efficacy**120 - 150 lm/W100 - 130 lm/W (Warm filters)**IP/IK Protection Rating**IP66 / IK08 - IK10IP66 / IK09**Surge Protection (SPD)**10kV / 10kA10kV / 20kA**Upward Light Output Ratio (ULORinst)**< 1%0% (Full Cut-off)**Dimming / Control**1-10V / DALI-2Zhaga / NEMA remote management### **Frequently Asked Questions (FAQs)** **1. Why is the surge protection device (SPD) value critical in LED lanterns?** Due to their outdoor location and connection to public networks, lanterns are vulnerable to transient voltage peaks caused by lightning strikes or grid switching operations. A surge protection device (**SPD**) of at least **10kV** is essential to protect the driver and LED module, preventing premature failures of the installation. **2. Which colour temperature is recommended to minimise impact on biodiversity?** Current regulations and recommendations from environmental bodies suggest the use of warm colour temperatures (**< 2700K**) or **PC-Amber LED** in rural areas or parks. These temperatures reduce emission in the blue spectrum, minimising insect attraction and disruption to the circadian cycles of local wildlife. **3. How is long-term sealing guaranteed in a manually opening lantern?** Sealing (**IP66**) is ensured through the use of high-recovery silicone seals and pressure-locking systems. It is vital that the lantern features a **breathing** system through valves that prevent internal pressurisation, extending the service life of electronic components. **4. What is the difference between a "Cut-off" lantern and a conventional one?** A **Full Cut-off** lantern is one designed not to emit any light above the horizontal plane (90°). This is a legal requirement in many communities to combat light pollution and improve efficiency, since all the emitted light is used on the useful surface.
